Hi everyone! I have a problem when I want to start Katalon, I get this log. I’m on a virtual machine with debian 10. Someone can help me to solve this problem? Thx a lot! BTW I’m a french student, I’m so sorry if my english is a little bit incomprehensible. !SESSION 2021-01-14 12:19:05.577 ----------------------------------------------- eclipse.buildId=unknown
